IMPROVEMENT 1N GHURNS.

To ALL wHoM 1T MAY ooMeEnN:

Beit known that I, SAMUEL T CURTISS, of El Paso, in the county ofWoodford, inthe State of Illinois, have invented a useful Improvementi'n Churns; and I do hereby declare that the following is a full andexact descriptionthereof,reference being had to theaccompanyingdrawings, and to the letters of reference marked thereon,making a. part of this specification, in whichi Figure 1 isa. sectionalvelevation of my invention.

Figure 2, a, plan view of the saine with-'the .gearing removed.

Figure 3, a. plan view of the dash removed from the othei-"partsof thechurn. 'Y

The nature of my invention consists in a peculiar dasher, having angularvertical projections, arranged to receive a. large quantity of cream attheir faces und sides, and' by'the motion of the dasher lforce itVthrough small openings, whereby a great amount of friction is obtainedwithvbut little motion.

' In order to give a correct understanding of` my invention, Ihevcmarked corresponding l'parts with similar letters, and will now give adetailed description. v l

A'rep'resents a common box-churn forV holding the cream, arrangedsimilarto those now in use, and therefore'needs no' particulardescription.

` K L represent a two-part lidinade of wood or other suitable material,'and to iitin a rabbet at the `inside cf the tcp'of box A, in the usualmanner,-and with a drum, Gr I J, projecting downward, in which ismade tooperate a fan, H, 'rigidly attached to and driven by a verticalshuft,r]3. i

` In the manufacture of thelid and drum, I find it most convenient tomake them botl1 of a single piece of two-inch plank-turned'out-in alathe before being clit through the centre, and afterward cut throughitsperiphery such a number-,of holes,N N, as'will allow the fari ,l-I toforce such a quantity of airinto the box A asfiiill kee'p the creamtherein cool, a semicirculu-r plate, M, being secured. to the half, K,of the lid, for the purpose of partially'coninirig the air when 'being'forced through the holes N.

The dusher-husapeculiar'construction, as follows:

A suitablepieces'of wood, F, igs. 1 and 2, is out away at V V, de., downto Z,`so as to leave large tspaces between thc projections X Fat thefaces TAS of the Vdesi/ier, and small openings, U, at' the bucle-oropposite sides o f the sume, whereby cream may readily enter at V, and'be forced'out at U, and `thuscreiite suchV an amount of friction as isnecessary to malie but-ter'speedily, a part of the wood being-left at'thc bottom, as seen at Z, for supporting the projections X, and givingtheilasher proper strength. The dasher-is rigidly attached to the shaftB, which bears'on a step, I), passes through the centre-nf the drum G* IJ, and is driven by means of eog-gecring C D, held in position by ariiron frame, E, attached to that part of the lid Ashown at K, the'arrangement of the gearing for driving the daslier being so vsimple astol be fully understood without further description. y v l VThe drum GIJ and fan H do notperform a new function, similar devices have beenused before for a like-purpose, and they have been described onlyto givea cle-.1r conception ofthe whole churn completed for use.

Having thus described my invention, I 'cla'iin`, aud desire tosecurc byLetters Pntentof the United Stateslhe dasher F, constructed and arrangedto operate .substantially :1s and for the purpose herein set forth.

` SAMUEL T. CURTISS.
